“No Spaces, Please”

When you are asked to enter your credit card number (or any other long series of digits), and the instructions are: Without Spaces.

Those long numbers are separated by spaces for a reason: to make them easier to read, and easier to remember. It’s a psychological thing called “chunking”. Easier to member several chunks than a long, long string of numbers, or letters, or what-have you.

And it would be so easy for the programer to remove the spaces. One simple php or c++ function would do it!
